Quantum nonlocality offers a secure way to produce random numbers: Their unpredictability is intrinsic and can be certified just by observing the statistic of measurement outcomes, without assumptions on how they are produced. To do this, entangled pairs generated measured violate Bell inequality with outcome statistics. However, after projective quantum measurement, entanglement entirely destr...

85Sr as radioindicator has been applied to strontium separation selectivity study using cisdicyclohexano-18-crown-6 (DCH18C6) extraction agent and picric acid counter ion with the aim contribute development of a rapid method extraction. The same used for fractionation in chosen soils by application Tessier- BCR sequential procedures. Experimental results have shown, that mentioned system is app...

To solve the problems of low precision weak feature extraction, heavy reliance on labor and efficiency extraction in X-ray weld detection image ultra-high voltage (UHV) equipment key parts, an automatic algorithm is proposed. Firstly, original denoised while retaining characteristic information defects by proposed monostable stochastic resonance method. Then, binarization achieved combining Lap...

Many interesting real-life mining applications rely on modeling data as sequences of discrete multi-attribute records. Existing literature on sequence mining is partitioned on application-specific boundaries. In this article we distill the basic operations and techniques that are common to these applications. These include conventional mining operations like classification and clustering and se...

In the domain of Bio medical Natural Language Processing (Bio-NLP), the information extraction and context sentiment identification are treated as emerging tasks. Several linguistic features like negation , uni-gram, bi-gram, Part-of-Speech (POS) have been used to extract the medical concepts and their sense-based context level information. Thus, in the present attempt, a hybrid approach which ...
